It's hard to believe that the Tigers, Mariners or even Fister himself were prepared for the results of this trade, so let's look at it on a player-by-player level…

The Major League Side

Doug Fister: Fister was 27 at the time of the trade and had less than two years of Major League service time. He'd been solid but not spectacular in his brief career, as he was the owner of a 3.81 ERA, 5.2 K/9 and 1.9 BB/9 in 378 innings for the Mariners. He was in the midst of his best season when he was dealt, having pitched to a 3.33 ERA in 146 1/3 innings. Fister channeled his inner Greg Maddux upon arriving in Detroit though, allowing just 14 earned runs with a 57-to-5 K/BB ratio in 70 1/3 innings for the AL Central champs. He's significantly upped his strikeout rate in Detroit, and all told he's given them 232 innings of 2.95 ERA ball with a 7.5 K/9 and 1.6 BB/9. Fangraphs pegs Fister's tenure in Detroit at a whopping 5.8 wins above replacement. He's under control for another three seasons and is set to earn $4MM this year after being eligible for arbitration for the first time this past winter.

David Pauley: Pauley is perhaps the forgotten man in this trade, although there's probably a reason for that. The right-hander threw just 19 2/3 innings for the Tigers after the trade, allowing 10 runs on 26 hits and six walks with just 10 strikeouts. Pauley was ulimately released by the Tigers the following spring and appeared in just 16 2/3 innings for the Angels and Blue Jays last year.

Charlie Furbush: Furbush floundered in Seattle's rotation in 2011, posting a 6.62 ERA in 10 starts. He thrived when moved to a bullpen role in 2012, however, thanks in large part to trading his curveball-changeup mix for a devastating slider to complement his heater. A triceps strain cost him a month of action last season, but when he was healthy he dominated lefties (.404 OPS) and held right-handed hitters in check as well (.637 OPS). Furbush can be a key bullpen piece in Seattle for a long time; he's not eligible for arbitration until the 2014-15 offseason, and he's under team control through 2017.

Casper Wells: Wells brought a good amount of power and some excellent defense to the Mariners. He clubbed 17 homers in addition to a .225/.304/.406 batting line (102 OPS+) and was eight runs above average in 893 innings for Seattle, per The Fielding Bible. Wells is capable of handling all three outfield positions, but the Mariners made the questionable decision to designate him for assignment last week to give Jason Bay a chance.

The Prospect Side

Francisco Martinez: Martinez was ranked as the Tigers' No. 4 prospect heading into the 2011 season, per Baseball America. He had reached Double-A at just 20 years of age — a rare feat that was a testament to the "live-bodied, athletic" label that BA slapped on him. He hit .310/.326/.481 for the Mariners' Double-A affiliate in 2011 following the trade, prompting BA to rank him as the team's No. 6 prospect entering 2012. BA praised his bat speed, stating that he "all the raw tools to fit the profile of an everyday third baseman, with the added bonus of plus speed." Martinez took a huge step backward in 2012, however, hitting just .227/.315/.295 in his second Double-A stint. He's dropped to No. 22 on BA's list of Top 30 Mariners prospects and No. 19 according to MLB.com's Jonathan Mayo. The Mariners tried Martinez in center field for 15 games in 2012 because of his plus speed, and Mayo notes that he'll play there exclusively in 2013. Mayo also points out that despite Martinez's struggles in 2012, he did improve his plate discipline — an area in which he'd previously struggled. He'll repeat Double-A in 2013, which isn't as grim as it sounds when considering he just turned 22 in September.

Chance Ruffin: Ruffin had to be included as a PTBNL because he had been selected by the Tigers in the 2010 draft (48th overall). He had entered the 2011 season as the Tigers' No. 7 prospect, per BA, and he carried the same designation with the Mariners into the 2012 season. Ruffin actually pitched 14 innings for Seattle in 2011 (3.86 ERA, 15-to-9 K/BB ratio) but reported to Triple-A in 2012. The results were ugly. The Texas alum posted a gruesome 5.99 ERA in 70 2/3 innings and saw his K/9 plummet from 11.1 to 6.9, while his BB/9 increased to 4.5. The brutal season was enough to drop him off Mayo's Top 20 list and knock him back to 27th on BA's Top 30 entering the 2013 season. BA cites erosion of his solid command in college and inconsitent mechanics as the reason for his downfall: "He lands on a stiff front leg and throws across his body, hurting his ability to locate his pitches where he wants. His long arm swing in the back and lower release point make it easy for lefthanders to pick up his pitches, and they hit .294/.348/.516 against him last year." The good news is that BA still likes his stuff, praising a 90-93 mph fastball that can touch 95 mph when needed and a plus slider with late break, which BA calls a true out pitch.

It's easy to see why the Tigers look like big winners in this trade, as the two key pieces of the deal for the Mariners have both taken large steps backward in their development. However, Martinez won't be 23 until September — the same month in which Ruffin will turn 25 — and the team does seem to have a solid bullpen piece already at the Major League level in Furbush. Martinez won't be at such a large age disadvantage in the Southern League this year, which could benefit his numbers. Ruffin will also open the season at Double-A as the Mariners plan to convert him to a starting pitcher (hat tip: Ryan Divish of the Tacoma News Tribune).

At the time of the trade, ESPN's Keith Law wrote that the Mariners did well to acquire such a strong package for Fister and Pauley, but clearly the scales have tipped in Detroit's favor. A rebound from Martinez or successful to transition to starting for Ruffin would make this trade look fair, but even if that happens I doubt you'll ever hear the Tigers or their fans complaining about the Doug Fister trade.

The Indians have overhauled their roster via free agency this season, adding the likes of Nick Swisher, Michael Bourn, Brett Myers and Mark Reynolds on Major League deals while bringing in notable veterans such as Matt Capps and Daisuke Matsuzaka on minor league pacts. At the 2011 Trade Deadline, however, the Tribe addressed its biggest needs in a different manner, dealing a package of four prospects to the Rockies in exchange for then-ace Ubaldo Jimenez.

Cleveland traded right-hander Alex White (22 years old at the time), first baseman Matt McBride (26 at the time), righty Joe Gardner (23 at the time) and lefty Drew Pomeranz (22 at the time) to Colorado in exchange for Jimenez, who had at least two and a half years of team control remaining on a low-cost contract. It was a steep price to pay, as Pomeranz and White represented the Indians' first-round picks from the previous two drafts. Gardner, meanwhile, had entered the season as Cleveland's No. 9 prospect, according to Baseball America.

Let's break the trade down player-by-player…

The Major League Side

Ubaldo Jimenez: To say Jimenez has been a disappointment in Cleveland would be putting things lightly. In 242 innings with the Indians, Jimenez has a 5.32 ERA, 7.6 K/9 and 4.5 BB/9. He entered 2012 with a career ground-ball rate near 50 percent, but saw that mark plummet to 38.4 percent last year. His once-blazing fastball has dropped from an average of 96.1 mph from 2009-10 to just 92.5 mph in 2012. His 4.8 BB/9 last season was a career-worst, and he led the American League in both losses (17) and wild pitches (16). In spite of all that, Indians GM Chris Antonetti exercised the team's $5.75MM club option on Jimenez this past offseason in hopes that he can rebound to something in the vicinity of the ace-caliber pitcher he once was. Jimenez is just 29 years of age still, and the price was right for Cleveland to give him another shot. His performance in 2013 will be one of they key factors in Cleveland's fate as their revamped roster makes a run at dethroning the reigning AL Central champion Tigers.

Drew Pomeranz: Pomeranz has a 5.01 ERA in 115 big league innings for the Rockies. His 1.9 K/BB ratio isn't exactly inspiring, but he was significantly better in a small minor league sample last season. Pomeranz posted a 2.31 ERA, 8.9 K/9 and 3.7 BB/9 in 50 2/3 innings between Double-A and Triple-A (46 2/3 of which were at Triple-A). He's still just 24 years old and is one year removed from entering the season as BA's No. 30 overall prospect and MLB.com's No. 24 ranked prospect. His fastball was down to averaging 91.2 mph season after previously sitting several ticks higher, but BA noted prior to 2012 that his ability to keep the pitch down in the zone and his deceptive delivery allowed the pitch to play at lower velocity. If Pomeranz can regain some of his velocity and/or hone his command of the strike zone, there's still time for him to blossom into the No. 2 starter BA and MLB.com projected him to be.

Alex White: Like Pomeranz, White struggled greatly in his Major League time with the Rockies. He posted an unsightly 6.30 ERA in 134 1/3 innings for the Rox from 2011-12. His marks of 5.9 K/9 and 4.5 BB/9 were significantly worse than his Triple-A rates of 7.8 and 3.0, respectively. White put the ball on the ground frequently in 2012 (54.1 percent) but lost more than a mile per hour off his fastball, dropping to a 91.2 mph average (identical to Pomeranz's, oddly enough). White was injured at the time of the trade and missed 82 games in the 2011 season with a strained ligament in his finger. How much that impacted his 2012 results remains to be seen, but he'll have a chance to prove he's worthy of a spot in a Major League rotation. It won't be with the Rockies, however, as the team traded White to the Astros along with Alex Gillingham to acquire ace setup man Wilton Lopez.

The Prospect Side

Joe Gardner: Gardner ranked as Colorado's No. 25 prospect prior to the 2012 season but dropped off the club's Top 30 list this year. He ranks 18th among Rockies' farmhands according to MLB.com's Jonathan Mayo, however, who calls Gardner's sinking fastball a "groundball machine" and notes that his change-up has some deception that leads to swings and misses. He also features a "slurvy" slider that Mayo grades out to be slightly better than his change but worse than his fastball. Gardner worked primarily as a starter at the Double-A level, but Mayo notes that he was very sharp in a five-appearance bullpen cameo. In total, Gardner compiled a 3.97 ERA, 6.4 K/9 and 2.5 BB/9 in 138 1/3 innings during his age-24 season. Today is his 25th birthday (Happy birthday, Joe!), and should have a chance to crack the big league roster this season with a strong minor league performance.

Matt McBride: McBride is currently Colorado's 33rd best prospect, according to BA, though they note that most of his value comes as a utility player due to the fact that he can play catcher on occasion. BA notes that he's a poor defender whether behind the plate, in right field or at first base, and that his ability to make frequent contact is accompanied by a lack of home run power. McBride hit .205/.222/.308 in 81 plate appearances for the Rockies last season, walking only once and whiffing 17 times. He did manage a .344/.365/.535 triple slash line at Triple-A. Still, at 27 years of age, he's not much of a prospect at this point, which was reflected in Colorado's decision to remove him from the 40-man roster in November.

That Joe Gardner and Matt McBride posted the best 2012 numbers of anyone involved in this trade is a telling sign. To be blunt, the deal currently doesn't look good for either side. A rebound campaign for Jimenez or a breakout from Pomeranz would alter that, but surely both teams had visions of aces in their minds when pulling the trigger on this deal — not a host of 5.00+ ERAs. Colorado picked up some value in flipping White for a strong bullpen arm with three years of team control remaining, though that could prove regrettable if White puts it all together as an Astro. For the time being, three teams are simply left hoping that they can squeeze some value out of the once highly regarded talent in this deal.

Zack Greinke made quite a few headlines this offseason by becoming the highest-paid right-handed pitcher in Major League history (Felix Hernandez has since topped him). The former No. 6 overall selection in the draft signed a six-year, $147MM with the Dodgers.

Greinke has long been a high-profile arm, thanks largely to his 2009 American League Cy Young Award. His 9.3 wins above replacement (Fangraphs version) that season were the most by any pitcher since Randy Johnson's 2004 season.

So it's no wonder that Greinke had a long list of suitors when it became evident that the Royals were going to trade him. Nor is it surprising that Greinke commanded a young shortstop, a young center fielder and a pair of right-handers that had both been first-round picks.

Zack Greinke: Greinke joined Shaun Marcum as one of two offseason acquisitions for the Brewers that offseason, as the team clearly had an "all-in" mentality entering the final season of Prince Fielder's contract. He broke a rib that offseason playing basketball, limiting him to 171 2/3 innings, but he pitched to a 3.83 ERA with an NL-best 10.5 K/9 when healthy. The Brewers ultimately finished with a 96-66 record, netting them an NL Central Division title. Greinke got his only taste of postseason baseball that year but allowed an unsightly 12 earned runs in 16 2/3 innings. The Brewers lost in the NLCS to the Cardinals, who would go on to win the World Series. Greinke hurled 123 more innings for the Brew Crew in 2012, pitching to a 3.44 ERA, 8.9 K/9 and 2.0 BB/9 before being traded to the Angels. GM Doug Melvin landed Jean Segura, John Hellweg and Ariel Pena in that deal, but that's a whole different post.

Yuniesky Betancourt: Betancourt hit a paltry .252/.271/.381 with the Brewers but still totaled 584 plate appearances in spite of that sub-par production. His defense was also well below-average, and the result was a mere 0.4 wins above replacement, per Fangraphs. Betancourt did manage to swat 13 homers that season — the second-highest mark of his career — but his lack of plate discipline and poor glove mitigated most of that value. He would go on to re-sign with the Royals as a free agent the following offseason and is now in the Phillies organization as a non-roster invitee.

Alcides Escobar: Milwaukee's No. 3 prospect at the time of the trade (per BA) Escobar has blossomed into the Royals' everyday shortstop, posting fWAR marks of 2.2 and 2.6 in his first two seasons with Kansas City. He doesn't walk often (4.2 percent), but he's posted a respectable .274/.311/.368 triple slash line with Kansas City. That includes significant improvement from 2011-12, as his OPS+ jumped from 74 to 98 between the two years. He's developed into an elite base-stealer, collecting 61 swipes in 75 tries (81.3 percent). In 2012, he went 35-for-40 (87.5 percent). The Fielding Bible evaluates Escobar's defense at +12 runs during his time with Kansas City, while Ultimate Zone Rating feels he's been closer to average. Still just 26 years old, Escobar has room for growth.

Lorenzo Cain: Cain's arrival as Kansas City's everyday center fielder was delayed by the acquisition of Melky Cabrera. Groin and thigh strains have cost Cain 98 games between his two seasons with the Royals, but he looks poised to take the reins as the team's everyday center fielder in 2013. It's a small sample, but Cain has a .266/.315/.410 batting line in 267 plate appearances with the Royals. His seven homers and ten steals translate to a 162-game average of 17 homers and 25 steals — a well-above average combination of power and speed for a center fielder. In 726 1/3 career innings in center, UZR/150 rates him at 14.4 runs above average, and The Fielding Bible agrees at +15 runs. He's excelled in the Minors for the Royals and is in the midst of an impressive Spring Training showing, but he'll already be 27 on April 13. Kansas City needs to let Cain play in order to determine if they have a long-term piece this season.

The Prospect Side

Jake Odorizzi: Odorizzi made his big league debut for Kansas City in 2012, but totaled only 7 1/3 innings. Those will likely be the only innings he ever throws for the Royals, as GM Dayton Moore included the now-22-year-old in the James Shieldstrade. Odorizzi is BA's No. 92 prospect in all of baseball, and he ranks 45th on MLB.com's Jonathan Mayo's version of the same list. BA ranks him fifth among Rays prospects, praising his four average pitches (fastball, slider, curve, change-up) but noting that he lacks a true out pitch. Both BA and Mayo agree that Odorizzi has a chance to become a reliable No. 3 starter, but his ceiling is limited by average offerings across the board.

Jeremy Jeffress: Jeffress' star has fallen considerably since he ranked as BA's No. 100 prospect prior to the 2009 season. Now 25 years of age, the Royals traded him to the Blue Jays for cash considerations this past November. Jeffress pitched 82 innings for Kansas City's Triple-A affiliate and maintained his strong strikeout rate (9.3 K/9) but walked too many (4.7 BB/9) and allowed nearly a hit per inning as well. He received a pair of call-ups to the big league club but walked 24 batters in 26 2/3 innings. He has the potential to be a power arm late in games, but he'll now look to fulfill that upside elsewhere.

In the end, the Brewers got an ace-caliber pitcher and an NLCS berth in exchange for the four prospects they dealt. Greinke managed to net them a trio of prospects including a new, promising shortstop to replace Escobar. Kansas City turned Greinke into an everyday shortstop, a promising center fielder and a pitching prospect that helped them acquire a new ace-caliber pitcher (Shields). However, the Royals are better positioned to compete with this top-of-the-rotation arm than they were the last time they had one.

Both teams fell a bit short of their best case scenarios (Milwaukee didn't win a World Series, and Kansas City cut ties with Jeffress for next to nothing), but this is a trade that definitely reaped benefits for each side.

MLBTR is launching a new series entitled "Transaction Retrospection" in which we'll take a look back on trades that have taken place to see how the players involved — including low-level minor leaguers — have fared in new settings and how the involved teams have been impacted. Last week looked at the Josh Reddick trade, but remember that you can look back on other trades using MLBTR's Transaction Tracker.

Matt Garza has been involved in his share of high-profile moves. Since being drafted 25th overall by the Twins out of Fresno State in 2005, Garza has switched organizations in two marquee deals, and he once again finds himself as a trade candidate. He's been with the Cubs for a little more than two calendar years, but it seems like longer given the amount of trade rumors which constantly contain his name.

Matt Garza: Garza immediately became one of the Cubs' best pitchers following the trade, and he showed it off with arguably the best season of his career. In 2011, Garza tallied 198 innings and established career-bests in ERA (3.32), K/9 (8.95) and HR/9 (0.64). He continued to display strong command and took a step toward establishing himself as an ace-caliber pitcher. Fangraphs pegged his value at a lofty 4.9 wins above replacement. His 2012 effort was derailed by a stress reaction in his pitching elbow after just 103 2/3 innings, however, which is likely the main reason that he wasn't traded at the deadline last July. While his elbow appears to be healed, Garza recently suffered a lat strain while facing live hitters and now stands to miss the first month of the 2013 season. Needless to say, that jeopardizes his No. 9 ranking on Tim Dierkes' free agent power rankings, but if he returns healthy and pitches well he's a midseason trade candidate.

Sam Fuld: Fuld's time in Tampa Bay got off to an incredible start, hitting .289/.358/.433 in the month of April. His defensive play, clutch hitting and surprising production spawned the Twitter hashtag "#LegendOfSamFuld," and the 29-year-old developed a cult following. He hit just .218/.292/.327 the rest of the way, however, and didn't improve in 107 plate appearances last season. He's competing for a roster spot with Tampa Bay once again this Spring.

The Minor League Side

Chris Archer: Archer came to the Rays as an erratic 22-year-old with an electric fastball. He still battles command issues, but he's progressed enough to rank as the game's No. 36 prospect according to Baseball America and No. 46 according to MLB.com's Jonathan Mayo. BA writes that his fastball sits 92-96 mph and is one of two "well above-average" pitches, the other being a devastating hard slider with "hard, cutting tilt and impressive depth." Mayo prefers Archer's fastball but echoes that both pitches can be plus at the MLB level. The two outlets agree that Archer's change-up development will be what determines if he's able to pan out as a top- or middle-of-the-rotation starter. Archer did make his MLB debut in 2012, firing 29 1/3 innings and whiffing 36 batters.

Hak-Ju Lee: Lee is ranked 90th in the game by BA and 56th by Mayo, good for fourth and fifth in the Rays' system, respectively. Mayo writes that defensively, the Korean-born shortstop is more than MLB-ready right now, but he needs more time to develop his line-drive swing. His plus speed is an asset which both Mayo and BA agree upon. Both think he'll be a legitimate base-stealing threat, even if his lack of home-run power limits his overall upside a bit. Lee offers an opposite-field approach at the plate but needs to develop a more patient approach. He stole 37 bases in 46 tries as part of a .261/.336/.360 season at Double-A in 2012.

Robinson Chirinos: A catcher by trade, Chirinos came to the Rays having ranked as the Cubs' No. 10 prospect according to BA. He regressed in 2011, however, hitting just .259/.343/.376 in 319 plate appearances — a vast departure from 2010's .326/.416/.583 line. Chirinos had a chance to make the Rays last Spring, but suffered a concussion that prevented him from playing a single game in the minors or Majors. He's with the team again in Spring Training this season, but his stock has obviously fallen.

Brandon Guyer: Guyer entered the 2012 season as the Rays' No. 11 prospect according to BA, thanks largely to the .312/.384/.521 triple slash line the outfielder posted at Triple-A in 2011. BA praised his combination of speed and power as well as his throwing arm, noting that he profiled nicely in right field but could handle center field as well. Guyer earned a call-up in early May, but disaster struck after just three games; he suffered a labrum tear that would end his season before he was able to back up his minor league promise.

Fernando Perez: Perez wasn't thought of as much of a prospect at the time of the trade, and indeed he never cracked the Cubs' big league roster. After hitting just .238/.312/.337 through 76 games for the Cubs' Triple-A affiliate, he was released. Perez latched on with the Mets, but fared even worse in 40 games for Triple-A Buffalo, hitting .188/.298/.250. He didn't play in affiliated ball last season.

Zach Rosscup: Rosscup hasn't cracked one of BA's Top 30 prospect lists for either team, nor has he appeared on one of Mayo's Top 20 lists. Now 24 years old, the southpaw suffered an arm injury midway through a promising 2011 season (2.54 ERA, 9.1 K/9). Upon returning in late 2012, he worked his way to Double-A and showed mixed results. Rosscup whiffed 29 batters in 22 1/3 innings at Double-A but also walked 19 and posted a 4.84 ERA. His 3.87 FIP showed more promise, and he'll likely open the 2013 season at that level.

The Rays have made a habit out of competing in one of baseball's toughest divisions despite having one of baseball's lowest payrolls, and trades like this are a large factor in that success. Executive VP of Baseball Operations Andrew Friedman dealt from a position of strength to acquire a host of prospects — two of which have developed into Top 100 prospects and two of which had their promising offensive potential limited by unforeseeable injuries. The Garza trade also paved the way for Jeremy Hellickson to join Tampa Bay's rotation and win 2011 AL Rookie of the Year honors.

The Cubs, meanwhile, got just the pitcher they were hoping for in Garza, but he too has been slowed by the injury bug. Garza would fit nicely atop Chicago's rebuilt rotation if he can return quickly, and he could net the team prospects this July if pitching well. Garza could also yield a first-round pick in 2014 if he turns down a qualifying offer, but his recent rash of injuries makes that a dicey proposition, as even the healthy Kyle Lohse has struggled to find a home due to his ties to draft pick compensation.

It's too early to say if one side got the better of this trade at this point, as Tampa Bay has yet to receive much value at the Major League level. However, the Rays seem to have positioned themselves for future success by moving a player when his value was near its peak.

MLBTR is launching a new series entitled "Transaction Retrospection" in which we'll take a look back on trades that have taken place to see how the players involved — including low-level minor leaguers — have fared in new settings and how the involved teams have been impacted. Remember that you can always look back at the players involved in transactions and check in on them yourself using MLBTR's Transaction Tracker.

Oftentimes, as spectators of the game, we focus on the immediate impact of trades rather than the long-term impact that some major transactions have on the teams involved. For example, while some undoubtedly remember all of the players involved in last year's Andrew Bailey–Josh Reddick trade between the Red Sox and Athletics, the majority of fans likely can't name all five players. The immediate impact was apparent in Reddick's success and Bailey's injuries, but there's more to this trade than just those two names.

Andrew Bailey: Bailey was supposed to take over as Boston's closer, but he would end up requiring thumb surgery in Spring Training and spend more than four months on the disabled list. Upon returning, he pitched to a disastrous 7.04 ERA in just 15 1/3 innings, walking eight and striking out 14 along the way. Bailey remains under team control through the 2014 season, so he'll have plenty of time to redeem himself and make this trade look better for Boston. However, he's been replaced as the closer following the offseason acquisition of Joel Hanrahan.

Ryan Sweeney: Sweeney went homerless in 219 plate appearances, batting .260/.303/.373 along the way. He played his typically strong brand of defense in Boston, posting an 11.6 UZR/150 and saving five runs over his 467 1/3 innings, per The Fielding Bible. Sweeney was non-tendered by the Red Sox this offseason but re-signed with the team on a minor league contract late last month.

Josh Reddick: Reddick exploded over the season's first half, batting a whopping .268/.348/.532 with 20 homers. While he slumped horribly in the second half, Reddick still finished with a .242/.305/.463 batting line with 32 homers. He was worth +22 runs per The Fielding Bible and posted an equally stellar 20.4 UZR/150. FanGraphs pegged Reddick's value at 4.8 wins above replacement. Reddick won't be arbitration eligible until after this coming season and is under team control through 2016.

The Prospect Side

Miles Head: Head ranks as the A's No. 7 prospect according to Baseball America and No. 9 according to MLB.com's Jonathan Mayo. The 21-year-old primarily played third base in the Oakland organization, but also has experience at first base. He hit a ludicrous .382/.433/.715 with 18 homers in 67 games for High-A Stockton before being promoted to Double-A Midland. He held his own as a 21-year-old at Double-A, batting .272/.338/.404 but whiffed in 32.1 percent of his plate appearances. BA praises his quick, compact swing and "outstanding" bat control, which create enough power to profile as a corner infielder. Head's lack of range and athleticism leave his future at third base in doubt, according to BA.

Raul Alcantara: Alcantara ranks as the team's No. 26 prospect according to BA and No. 11 prospect according to MLB.com. After a dominant 2011 in Boston's organization, Alcantara struggled with Oakland's Class-A affiliate in Burlington in 2012. He pitched to a 5.08 ERA, 5.0 K/9 and 3.3 BB/9 in 102 2/3 innings of work. BA has his fastball at 90-95 mph, and they also praise his change-up's depth and armside run. Both Mayo and BA agree that Alcantara's breaking pitches need work but praise his delivery and command. Alcantara turned 20 in December, so it would seem there's plenty of time to hone his secondary pitches and develop a bit more movement on his fastball.

The trade also had an impact on other players already in the organizations. Bailey's injury forced Alfredo Aceves into the closer's role in Boston for the first time, which had unspectacular results. The acquisition of Bailey was supposed to give the Red Sox enough depth to shift Daniel Bard into the starting rotation. Bard struggled, however, and when he returned to the bullpen after a Triple-A stint, he allowed 14 runs in six innings of relief pitching.

Reddick's acquisition, meanwhile, replaced the power production of the departing Josh Willingham — who signed as a free agent with the Twins — and vastly improved Oakland's outfield defense in the process. Willingham's departure, the Bailey trade and the Gio Gonzalez trade allowed the A's to invest four years and $36MM in Cuban hotshot Yoenis Cespedes.

The trade looks bleak for the Red Sox right now, but one of the beauties of transactions like this is the seemingly endless web they spin. For example, a strong season from Bailey could lead to another trade, causing the cycle to start all over again.
